The processor is STM32 single-chip microcontroller in the present embodiment.
The host computer and slave computer is allowed to realize above-mentioned function, slave computer executes the execution command instruction process of host computer
Figure can refer to Fig. 6.It is specific as follows:
When writing the program of STM32 single-chip microcontroller, it is necessary first to which the thing done is exactly to initialize single-chip microcontroller.Here, needs pair
The operation that STM32 single-chip microcontroller is initialized.Firstly the need of the serial ports for defining STM32 single-chip microcontroller, it is specified that the relevant parameter of serial ports
Such as baud rate, simultaneously as needing single-chip microcontroller to make a response immediately when there is information to pass through serial communication, so needing to string
Port communications carry out out interrupting setting.Also need to define the I/O mouth that hardware needs to use simultaneously, in order to facilitate program to I/O mouthfuls
Operation change corresponding I/O mouthfuls of state by being operable to the variable by I/O mouthfuls of address assignment to variable.Pass through
After serial ports definition, the information that host computer sends over can be received by defining an array, by its step-by-step storage to number
In the corresponding position of group.
In order to distinguish command instruction and displacement commands, avoids the two from obscuring, used judgement sentence.On in order to prevent
Position machine continuously sends the generation that information causes information transmitting the situation of mistake occur, and host computer once only sends a line and refers to
It enables, if there is multirow command instruction needs to send, slave computer is needed to first carry out current instruction, send special instruction and tell
Host computer oneself has executed the current command, and host computer just will continue to send next instruction to slave computer at this time.
Before executing displacement commands, also need to judge by way of judgement whether to be displacement commands.If present instruction is
Displacement commands, it is necessary to present instruction be interpreted according to the format of displacement commands.The position that host computer has been generated
The format of information is explained, and format is " X/Y+ incremental displacement+designator ".Slave computer is by carrying out array first
Judgement is then read out four Bit Shift information, passes through formula it can be concluded that the displacement commands are which corresponding reference axis
The distance that should be moved at this time is calculated, formula is as follows:
△ X=array [2] * 1000+ array [3] * 100+ array [4] * 10+ array [5]
Instruction control the first, second, and third ball slide unit is assigned by host computer described in the above method back and forth to move
It is dynamic, realize quickly positioning, rapid processing.
In the present embodiment, the angle that first driving equipment 24 rotates is controlled to the rolling by the above method
The displacement of pearl slide unit 27 is more accurately controlled, wherein first driving equipment 24 drive the ball slide unit 27 into
The mobile minimal error of row can achieve 12um, and according to production requirement, the driving of first driving equipment 24 ball is sliding
Platform 27, which carries out mobile selectable precision interval, 12um~50um, and the processing offer that may be implemented to micro-aperture is higher
Machining accuracy and faster process velocity.
In conclusion the utility model allows the perforating device to carry out three axis by the way of three screw rod slide unit components
Movement.The utility model drives the screw rod stepper motor of screw rod rotation can be with by configuration processor i.e. STM32 single-chip microcontroller
